Purpose: Determinants of mandibular movements, like condylar inclination and incisal guidance, should be considered in the fabrication of restorations in occlusion to prevent posterior excursive occlusal interferences. The aim of this study was to investigate differences in the occlusal morphology of the right mandibular molar resulting from high, average, and low values of settings for determinants of anteroposterior and transverse mandibular movement using a virtual articulation model. Material and Methods: The articulation functionalities of computer integrated restorative technology by imaging and new acquisition (CYRTINA®, Oratio B.V., Zwaag, The Netherlands) were used as a tool to examine the potential effect of determinants of mandibular movement on occlusal molar design. High, average, and low values for condylar guide inclination, incisal guide angle, and intercuspal contact area (antero-posterior determinants) and laterotrusion, mandibular lateral translation and intercuspal contact area (transverse determinants) were introduced and differences in molar morphology studied. The latter was done by comparing mesiodistal and buccolingual sections of the occlusal designs. These interocclusal differences were quantified as differences in frequency of occlusal distance intervals in an interocclusal range of 1 mm, measured from the occlusal surface of the molar model. The vertical distance with which a standard crown in occlusion had to be corrected to avoid interferences was calculated. Results: Among all parameters, the ipsilateral and contralateral mandibular lateral translation, sagittal condylar guide inclination, the ipsilateral laterotrusion and the incisal guide angle give substantial occlusal surface corrections. The high setting for the ipsilateral mandibular lateral translation required most correction. Conclusion: High and low setting values of mandibular movement determinants require considerable adaptation of the occlusal surface of a crown to prevent occlusal disturbances.
